RISA Linear Method for Analyzing Lightning Field Changes
Publisher: American Meteorological Society
Abstract: A constrained, least-squares method for analyzing multiple-station measurements of lightning field changes (?Es) is introduced. Previous methods have attempted to fit the spatial pattern of lightning ?Es using nonlinear ...
Cloud-to-Ground Lightning and Surface Rainfall during the Great Flood of 1993
Publisher: American Meteorological Society
Abstract: Relationships between cloud-to-ground (CG) lightning, as reported by the U.S. National Lightning Detection Network (NLDN), and surface rainfall, as reported by National Weather Service (NWS) cooperative observers, have ...
Electrostatic Field Changes Produced by Florida Lightning
Publisher: American Meteorological Society
Abstract: The electrical behavior of thunderstorms triggered by local heating and sea-breeze convergence, a low pressure disturbance, and a weak frontal passage has been studied at the NASA Kennedy Space Center, Florida. A nonlinear ...
A Portable, PC-Based System for Making Optical and Electromagnetic Measurements of Lightning
Publisher: American Meteorological Society
Abstract: A digital video camcorder, a four-channel analog-to-digital (A/D) converter, and a GPS time/position receiver have been interfaced to a portable personal computer (PC) to provide a mobile data-collection platform for making ...
Broadband Antenna Systems for Lightning Magnetic Fields
Publisher: American Meteorological Society
Abstract: Broadband magnetic field antenna systems which can resolve submicrosecond structure in lightning waveforms are described. Correlated data on the magnetic and electric fields produced by distant lightning are presented and ...
Average Diurnal Variation of Summer Lightning over the Floirida Peninsula
Publisher: American Meteorological Society
Abstract: Data derived from a large network of electric field mills have been used to determine the average diurnal variation of lightning in a Florida seacoast environment. These data were obtained at the NASA Kennedy Space Center ...
A Gated, Wideband Magnetic Direction Finder for Lightning Return Strokes
Publisher: American Meteorological Society
Abstract: A magnetic direction finder has been developed which utilizes only the initial few microseconds of wide-band return stroke waveforms to provide accurate directions to the channel bases of lightning discharges to ground. ...
Detecting Multiple Ground Contacts in Cloud-to-Ground Lightning Flashes
Publisher: American Meteorological Society
Abstract: Video recordings of cloud-to-ground (CG) lightning flashes have been analyzed in conjunction with correlated stroke reports from the U.S. National Lightning Detection Network (NLDN) to determine whether the NLDN is capable ...
Toward Development of Improved QPE in Complex Terrain Using Cloud-to-Ground Lightning Data: A Case Study for the 2005 Monsoon in Southern Arizona
Publisher: American Meteorological Society
Abstract: he relationship between convective precipitation and cloud-to-ground (CG) lightning is examined over a study area in southwest Arizona and northwest Mexico. Using seasonal-to-daily and hourly time resolution, the National ...
